Skyfire live

Erm.....it's ok for a small show, but for a big one, I say no. Why, lost the keyplayer?

Pre-recorded stuff has no feeling. I'd rather hear you without keyboards at all or with another guitar doing the keyb stuff.
 
Get ARM implants (2 of them) and install keys along your guitar and fretboard. Another brain might be handy. But I agree with above, better Skyfire w/out keyboards than no Skyfire at all! Though I spose it doesn't matter (you won't be visiting the UK anytime very soon! =( )

Still though, those keyboards rock...I guess all guitarists are multi-talented.
 
I say go for it....I've seen bands go live with recorded stuff, and its no biggie. I know Nile uses sequencers for all of their keyboard/atmospheric stuff live....
